Aussies could be walking around with up to $650 in their pockets, with one expert urging people to keep an eye out for a rare $2 coin

The 2013 Queen's Coronation coin, marked with a crown with purple circles around it, is worth up to hundreds more than its face value.

Australians could be walking around with a small fortune in their pockets, with one coin expert urging people to keep an eye out for a rare $2 coin.

The 2013 Queen’s Coronation coin, which is distinguished by a crown with purple circles around it, is worth up to hundreds more than its face value.

Coin collector Michael McCauley said about a million of the coins were put into circulation, and it is typically worth between $30 to $86.

But a select run of close to 35,000 coins were produced for coin collectors with a special C mint mark.

The special mark significantly upped the value of the coin to between $440 and $650, Mr McCauley said in a TikTok video.

“They didn’t make many of the C mint marks, and they were just for collectors,” Mr McCauley said.

“So a million of the coins were made for circulation, but only 34,967 produced for coin collectors with the C mint mark.”

He said they were ““pretty hard to find”.

“Definitely one to keep an eye out for and if you find them hold onto them maybe even try and sell ‘em,” he said.

The coin was officially launched in 2013 for the 60th anniversary of Queen Elizabeth’s coronation.

“The uncirculated version of Australia’s first purple-striped coin, and the inspiration behind the Mint’s Colourful Change program, has been pressed with a Canberra ‘C’ Mintmark,” the Royal Australian Mint’s September 2013 Mint Issue stated.

“The design features a stylised representation of St Edward’s Crown surrounded by circles including a pattern of purple stripes.”

It was sold for $12.95 when it was first released, according to the Mint Issue.
